“The electrical layout for the MK 1 scooter is fairly straightforward. Everything starts from the 12S 4p cylindrical battery module. A Cooper Bussman 120A circuit breaker sits between the battery and the rest of the scooter. Note that, while there are a number of DC circuit breakers out there, VERY few actually tolerate vibrations. I found this out the hard way when I started using [link]. The first hint of vibration and the breaker tripped, which, made it fairly hard to use. The headlight I chose is a fairly awesome 30W led setup with a 30 degree beam path. It has an onboard dc/dc, but unfortunately its max input voltage is 30V. I used a 40W dc/dc to bring the module voltage back down to 12v DC, which is useful for driving the LED assembly as well as 12v accessories (if I opt for adding a sealed 12v cigarette lighter outlet). Finally a linear regulator feeds the 5v logic for the three phase sensorless controller and throttle assembly. “

This looks insanely fun, I used to have one of those huge, old scooters when I was a kid…

They should build a snowmobile like studded track for the snow scooter’s rear wheel, they could at least tackle deeper snow as well as gain MUCH more traction… All in all, great and insanely well detailed build…
